Several weeks ago I picked up “The Elegant Universe” because I thought it would have information on The Ultimate Theory. Soon afterwards, I picked up “How to Teach Physics To Your Dog” in order to get ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

The classic double-slit experiment of quantum physics involves shining light through two narrow gaps to show that it can behave as a wave – now it seems the slits can be entirely replaced by a single ...

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...
